Gripnail Bang-On Pins

Elgen’s Bang-On Pin is a unique mechanical fastener used to attached insulation to sheet metal. It was specifically designed to fasten acoustical duct liner to the inside of heating, ventilating and air conditioning ductwork. This operation generally takes place when the ductwork is being manufactured. The Pins are plated with .0002" to .0003" of zinc and receive a final chromate dip. This plating exceeds current SMACNA standards for corrosion resistance.
